2-[[[4-(methylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl]aminocarbonyl]aminosulfonyl]benzoic acid, methyl ester, m.p. 195°-197° C.(d); and

2-[[[4-(methylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl]aminocarbonyl]aminosulfonyl]benzoic acid, ethyl ester, m.p. 181°-183° C.(d).

DETAILED DESCRIPTION OF THE INVENTION Synthesis

The compounds of Formula I can be prepared by reacting an appropriate sulfonyl isocyanate II with the appropriately substituted aminoheterocycle III, as shown in Equation 1. R, X, Y, Z and L are as previously defined. ##STR9##

The reaction is best performed in an inert solvent such as methylene chloride or toluene at 25° to 100° C., for 1 to 24 hours. Isolation of the product can be achieved by concentrating the solution and trituration with an appropriate solvent such as butyl chloride.

Alternatively, compounds of Formula I may be prepared by reacting the sulfonamides of Formula IV with the carbamates of Formula V (R'=CH₃) in the presence of an excess of trimethylaluminum, as shown in Equation 2, where L, R, X, Y and Z are as previously defined, provided R₁ is other than CO₂ R₁₀. ##STR10##

The reactions are best performed in an inert solvent such as methylene chloride at the reflux point of the solution (40° C.) for 10 to 24 hours. Isolation of the product is best achieved by exposing the reaction mixture to acetic acid, separation of the layers and concentrating the organic layer to a solid.

Alternatively, compounds of Formula I can be prepared by exposing a phenyl carbamate V (R'=Ph) to the sulfonamide IV in an appropriate solvent such as dioxane at 25° to 100° C. in the presence of a strong base such as 1,8-diazabicyclo[5.4.0]undec-7-ene; acid workup affords the desired product. See EPO Publication No. 44,807 for details. The required carbamates (V) can be prepared from the corresponding amines III and dimethyl or diphenyl carbonate or methyl or phenyl chloroformate and a suitable base such as sodium hydride.

The sulfonyl isocyanates II used in the preparation of I are known in the art and can be prepared by known methods. For example, isocyanates can be prepared by exposing an appropriate benzene or heterocyclic sulfonamide to phosgene in the presence of an alkyl isocyanate and an amine catalyst such as 1,4-diazabicyclo[2.2.2]octane at the reflux point of the solvent. See H. Ulrich and A. A. Y Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI, p. 223-241, Academic Press, New York and London, W. Forest Ed.

The sulfonamides IV used in the preparation of I are also known in the art and can be prepared by known methods. For example, exposure of a sulfonyl chloride to ammonium hydroxide results in the formation of the corresponding sulfonamide, e.g., Crossley et al., J. Am. Chem. Soc., 60, 2223 (1938). The appropriate sulfonyl chlorides are prepared by several methods. For example, treatment of a substituted aromatic or heterocyclic ring with chlorosulfonic acid in carbon tetrachloride results in the formation of the sulfonyl chloride. See Clark et al., Org. Synth. Coll., Vol. 1 2nd Ed. 1941, p. 85.

An alternative method of preparation of sulfonyl chlorides can be achieved from an appropriate amine. Diazotization of an amine with sodium nitrite in acid, followed by exposure of the resulting diazonium salt to sulfur dioxide in the presence of cuprous chloride results in the formation of a sulfonyl chloride. See H. L. Yale and F. Sowinski, J. Org. Chem., 25, 1824 (1960).

The heterocyclic amines III, where X, Y, Z and R are as previously defined may be prepared as outlined in Equation 3. ##STR11##

Reaction of dichloride VI with the appropriate secondary amine in acetone affords the aminated product VII. Subsequent exposure of VII with the appropriate alcohol in the presence of a suitable base such as potassium hydroxide affords the desired heterocycle III (where T is CF₃, CHF₂ or CH₂ F).

The starting amine heterocycles VI are known in the art. For further details of their preparation see The Chemistry of Heterocyclic Compounds, "Interscience Publ., New York and London; P. J. Brown, "The Pyrimidines", Vol. XVI and E. M. Smolin and L. Rapoport, "s-Triazines and Derivatives", Vol. XIII.

The heterocyclic amines III where R is a methyl group may be prepared from the corresponding compounds where R is hydrogen by known methods. An example of this type of transformation is described in: J. Chem. Soc. Perkin I, 1569 (1981).

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide or carbonate). Quaternary amine salts can be made by similar techniques.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration.

Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble, e.g., a potassium, sodium or calcium salt.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

The following examples teach the synthesis of some of the compounds contained within this invention in greater detail.

EXAMPLE 1 2-Amino-4-chloro-6-methylamino-1,3,5-triazine

A solution of 2-amino-4,6-dichloro-1,3,5-triazine (0.2 mole) in 200 ml reagent grade acetone was cooled to 0° C. Two equivalents of 40% aqueous methylamine were added dropwise keeping the temperature less than 10° C.; solids precipitated during the addition. The reaction was then warmed to room temperature and stirred overnight under N₂.

The mixture was poured onto 800 ml of ice-water and the insolubles were filtered off and washed with distilled water. The solid was dried overnight over P₂ O₅ in a vacuum dessicator. The resulting product named above had the following characteristics: m.p. 258°-260° C. (decomp.); NMR (CDCl₃, DMSO-d₆): δ 2.8, d, (NHCH₃); 6.8-7.65, mt, (NH₂ +NHCH₃).

EXAMPLE 2 2-Amino-4-methylamino-6-trifluoroethoxy-1,3,5-triazine

2-Amino-4-chloro-6-methylamino-1,3,5-triazine (0.2 mole) was slurried in 80 ml of 2,2,2-trifluoroethanol at room temperature. Potassium hydroxide pellets (0.2 mole) were added portionwise and the mixture was stirred at room temperature overnight. The following day the reaction was heated at gentle reflux for 2 hours during which time the solids gradually dissolved. The solution was cooled and the solvent was removed under vacuum. The residue was washed with water and filtered to give 20.9 g shining off-white crystals of the product named above with the following characteristics: m.p. 204°-205° C. NMR (DMSO-d₆): δ 2.75, d, (NHCH₃); 4.8, q, (OCH₂ CF₃); 6.5-7.3, m, (NH₂ +NHCH₃).

EXAMPLE 3 2-[[[4-(Methylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl]aminocarbonyl]aminosulfonyl]benzoic acid, methyl ester

2-Carbomethoxybenzenesulfonyl isocyanate (0.5 g) was dissolved in 5 ml of methylene chloride. The aminoheterocycle (0.46 g) prepared in Example 2 was added and the mixture was stirred overnight under nitrogen at room temperature. The resulting solids were filtered off, washed with methylene chloride and dried to give 0.54 g of ˜80% pure subject compound; m.p. 195°-197° C. decomp. No attempt was made at further purification. The resulting product named above had the following characteristics: IR (nujol) showed carbonyl bands at 1723 cm⁻¹ and 1740 cm⁻¹. NMR (CDCl₃, DMSO-d₆): δ 2.9, m, (NHCH₃); 3.8, s, (CO₂ CH₃); 4.9, m, (OCH₂ CF₃); 7.7-8.4, m, (aromatic H's) plus ˜20% heterocycle.

FORMULATIONS

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

Utility

Test results indicate that the compounds of the present invention are highly active preemergent or postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as wheat. Alternatively, the subject compounds are useful to modify plant growth.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.01 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modification or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with any other commercial herbicide; examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow. ##STR39##

TEST A

Seeds of crabgrass (Digitaria spp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea spp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, sugar beet, cotton, rice, wheat and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

B=burn;

C=chlorosis/necrosis;

D=defoliation;

E=emergence inhibition;

G=growth retardation;

H=formative effect;

U=unusual pigmentation;

X=axillary stimulation;

S=albinism; and

6Y=abscised buds of flowers.

TEST B Postemergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Woodstown sandy loam soil. One pan was planted with blackgrass (Alopecurus myosuroides), sugar beets, nutsedge (Cyperus rotundus) tubers, crabgrass (Digitaria sanguinalis), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), and giant foxtail (Setaria faberii). The other pan was planted with wheat, cotton, rice, corn, soybean, wild oats (Avena fatua), cocklebur (Xantium pensylvanicum), morningglory (Ipomoea hederacea), johnsongrass (Sorghum halepense) and barnyardgrass (Echinochloa crusgalli). The plants were grown for approximately fourteen days, then sprayed postemergence with the chemicals dissolved in a non-phytotoxic solvent.

Preemergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Woodstown sandy loam soil. One pan was planted with blackgrass (Alopecurus myosuroides), sugar beets, nutsedge, crabgrass, sicklepod, teaweed, jimsonweed, velvetleaf, and giant foxtail. The other pan was planted with wheat, cotton, rice, corn, soybeans, wild oats, cocklebur, morningglory, johnsongrass, and barnyardgrass. The two pans were sprayed preemergence with the chemicals dissolved in a non-phytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for 28 days, then all treated plants were compared to controls and visually rated for plant response.

Response ratings are based on a scale of 0 to 100: where 0=no effect, and 100=complete control. A dash (-) response means no test.

Response ratings are contained in Table B.
